The latest edition of Inspire Magazine -- an English-language online magazine published by Al Qaeda in the Arabian Peninsula-- appears to show an effort to capitalize on the Boston Marathon bombings.
"O American people, your security will not be attained by denying security to other peoples, attacking them or oppressing them," according to Inspire, The New York Post reported. "Your security is in the hands of the fools among you who rule you with oppression and aggression. Know that oppression and aggression come back upon the heads of those who use them."
A U.S. official told Fox News in April that Tamerlan Tsarnaev, 26, and his brother, Dzhokhar Tsarnaev, 19, built the Boston bombs with instructions from Inspire.
The publication is believed to have been started by Samir Khan, a U.S. citizen who moved in 2009 from his family's home in North Carolina to Yemen, where he was later killed in a U.S. drone strike along with Al Qaeda leader Anwar al-Awlaki. The magazine includes articles penned by Khan and others, like "Make a Bomb in the Kitchen of Your Mom."
The magazine is released through online jihadist forums -- some of which are open, while others are password protected, according to terrorism researchers.
But one issue of Inspire encourages readers to seek out its information from non-jihadist websites, like blogs and even news outlets -- which publish the magazine's content -- so as not to attract the attention of law enforcement monitoring the forums, a counter-terrorism source previously told FoxNews.com.
